Description

Technical Field

[0001] This utility model belongs to the field of automotive emergency equipment technology, specifically relating to a universal vehicle-mounted flashlight. Background Technology

[0002] Flashlights are a common tool in people's lives. Currently, with the rapid development of smartphones, although the uses of flashlights have been greatly limited, they still hold an irreplaceable position in certain areas. For example, when driving, unexpected situations sometimes arise, and if the light is not strong enough, a car flashlight is indispensable for vehicle inspection. However, most existing car flashlights achieve constant power output through circuitry, resulting in shorter operating times for the same battery capacity. Utility Model Content

[0003] To enhance the illumination time of vehicle flashlights, this invention provides a universal vehicle flashlight with long battery life, low cost, and wireless charging capability.

[0004] A universal vehicle-mounted flashlight has a top cover and a base plate connected to form a chamber. The upper surface of the top cover is provided with a cover plate, on which buttons and multiple light guides are installed. A first circuit board is installed inside the chamber and vertically fixed to the base plate. Two sets of light sources are respectively arranged on both sides of the first circuit board, and two sets of lens assemblies are installed in front of the two sets of light sources for SOS illumination. The front end of the second circuit board is fixed to the first circuit board, and the rear end is fixed to the base plate via a support. A light source is provided at the lower front of the second circuit board for flashlight illumination, and the light is emitted through a transparent mask via a reflector assembly. The second circuit board is connected to the button and multiple photoconductive contacts to realize the control of the vehicle flashlight switch. A wireless charging plate is also fixed to the upper surface of the base plate. The bottom end of the wireless charging plate is fixed to the support part, and the wireless charging battery is installed on the wireless charging plate.

[0005] Technical effects: This invention, by adding wireless charging functionality, is applicable to wireless charging areas for all vehicle models. Compared to the existing technology's 2-hour illumination duration, it offers more than 4 hours of continuous use. Utilizing a rectangular reflector assembly with a 120° LED beam angle, it avoids glare from direct LED light. Furthermore, the reflector assembly is made of aluminum-plated components, reducing light loss by reflecting the LED light source onto the reflector, further achieving high-efficiency lighting with a light utilization rate >60%. The overall dimensions are 117mm x 50mm x 27cm, while the flashlight thickness is controlled at 27mm. Its flat shape conforms to most existing wireless charging areas, making it easy to hold, operate with one hand, and carry. Attached Figure Description

[0012] The components include: top cover 1, bottom plate 2, cover plate 3, button 4, light guide 5, transparent mask 6, reflector assembly 7, lens assembly 8, first circuit board 9, second circuit board 10, support part 11, wireless charging plate 12, and wireless charging battery 13. Detailed Implementation

[0013] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0014] This embodiment provides a universal vehicle-mounted flashlight, such as... Figures 1 to 6 As shown, it mainly includes a top cover 1, a base plate 2, a cover plate 3, a button 4, a light guide 5, a transparent face mask 6, a reflector assembly 7, a lens assembly 8, a first circuit board 9, a second circuit board 10, a support part 11, a wireless charging plate 12, and a wireless charging battery 13. All components work together to achieve the flashlight's long battery life, multi-functionality, and portability.

[0015] The top cover 1 and the bottom plate 2 are connected by concealed screws to form a closed chamber. A sealing ring is installed at the connection to ensure the overall airtightness of the structure. In addition, the internal electronic components are all sealed with adhesive, thus achieving the overall waterproof function of the flashlight and enhancing its reliability and durability in the changing environment of the vehicle (such as rain and humidity).

[0016] Inside the enclosure, the first circuit board 9 is vertically fixed to the base plate 2. Two sets of light sources for SOS distress signals are respectively set on both sides of it. A lens assembly 8 is installed in front of each light source to focus and guide the light, ensuring that the light pattern and signal of the SOS signal are clear.

[0017] The front end of the second circuit board 10 is fixedly connected to the first circuit board 9, while the rear end is fixed to the base plate 2 via the support part 11. A light source for conventional lighting (flashlight function) is located below the front of the second circuit board 10. The light emitted by this light source is reflected and distributed by the reflector assembly 7 before being evenly emitted through the transparent faceplate 6 in front. The reflector assembly 7 is specially designed in a rectangular shape to accommodate the approximately 120° emission angle of the LED light source, effectively collecting side light and guiding it directly forward. The reflector surface is coated with aluminum, resulting in high reflectivity. This converts direct LED light into reflected light, avoiding glare that may be caused by direct light and improving user comfort. Furthermore, it significantly reduces light loss, increasing the light efficiency to over 60%, achieving high-efficiency lighting.

[0018] The top cover 1 has a cover plate 3 on its upper surface, on which a button 4 and multiple light guides 5 are mounted. The second circuit board 10 integrates a mechanical button corresponding to the button 4, and multiple LED indicator lights, preferably surface-mount LEDs, connected one-to-one with the multiple light guides 5. The user can control the flashlight's on / off state and mode switching (e.g., constant light, SOS) by pressing the button 4 to trigger the mechanical button. Simultaneously, the status of the LED indicator lights (e.g., battery level, charging status, operating mode) is transmitted to the outside through the corresponding light guides 5, providing the user with intuitive visual feedback.

[0019] The flashlight's core power source is a wireless charging battery 13, which is mounted on a wireless charging plate 12 fixed to the upper surface of the base plate 2. The bottom end of the wireless charging plate 12 is fixed to the support part 11 to ensure structural stability. The wireless charging plate 12 supports common wireless charging standards such as Qi, allowing the flashlight to be conveniently placed in the charging area of ​​most vehicles equipped with wireless charging capabilities for charging, eliminating the need to find and unplug charging cables, greatly improving the convenience of in-vehicle charging. This is achieved by combining a highly efficient linear circuit with a wireless charging battery.

[0020] The first circuit board 9 and the second circuit board 10 are linear circuit PCBs. Compared with simple constant power circuits, they can more intelligently adjust energy consumption according to actual needs when the battery capacity is the same.

[0021] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
